Subject [jira] [Created] (FLEX-33157) Sort class: _fields and fieldList variables can be out of sync
Date Fri, 03 Aug 2012 12:55:02 GMT
Robert Bar created FLEX-33157:

             Summary: Sort class: _fields and fieldList variables can be out of sync
                 Key: FLEX-33157
                 URL: https://issues.apache.org/jira/browse/FLEX-33157
             Project: Apache Flex
          Issue Type: Bug
          Components: Spark: Sort and SortField
    Affects Versions: Adobe Flex SDK 4.5 (Release)
            Reporter: Robert Bar
            Priority: Minor
             Fix For: Adobe Flex SDK 4.5 (Release)

NOTE: the issue exists in both, mx and spark Sort classes.

Sort.findItem function is not able to configure search criteria and skips a block of code
due to outdated fieldList variable. It often happens when the user sorts the AdvancedDataGrid
by clicking on a certain column header. In the shortest scenario you can reproduce it (without
AdvancedDataGrid) as follows:
1. create Sort object and assign an empty array of SortField objects to it 
->  _fields and fieldList are both empty
2. add SortField object directly to the array
->  _fields length is 1, BUT  fieldList length is 0 (BUG) which disallows findItem() operation
to configure search criteria
